Just discovered this topic.
I ll be really happy to help if you re still chasing this MP dumps bugs.
I do have a reproduction rate of 100% ( so I feel can of cursed when I read that is a really rare bug)
Anyway here are the reproducton steps:
- Start Sin
- Start an online game
- PLay for about 2h or more
- Go back to the lobby
- Restart straight away a new game.
- Wait for the bug
So, if you guys are still looking for this I would be more than happy to play with some people with the "test verison" exe installed.
let me know,
